ABSTRACT:
A method for molding articles, particularly tires, of different diameters/circumferences including a plurality of pitches defining a mold cavity, the pitches having transverse faces in generally face-to-face abutment in a closed position of the mold cavity, and at least several of the pitches being of different lengthwise sizes. The pitches in the closed position of the mold cavity defining a predetermined mold configuration which includes portions at angles to the length of the article molded in the mold cavity. The mold configuration matches lengthwise across all of the transverse faces irrespective of the location of the pitches relative to each other and irrespective of the number of the pitches. The latter arrangement permits articles, such as new or retread tires, of different lengths but of the generally same predetermined mold configuration to be molded in a single mold.
